Typically in AWS environment, we use CodePipeline as the orchestrator to build, test and deploy our application/service. But in some scenario such as deploying static websites, we may just need to achieve simple continuous deployment. In these cases, we don’t need the full blown deployment pipeline for staging and approval process. We can simply use […]
